Show detailed report? If checked, you will see the results for each possible HP IV if they would yield different results, along with the game's approximation of your chances in each case and how many times the ball is going to wobble if the capture fails; otherwise, you'll see the overall chance assuming you know nothing about the IV. This is only very meaningful at full or less than 1/3 HP, since the approximation of the Pokémon's current HP is not exact.
